WebRTC - create PeerConnectionFactory object

Question

i previously used WebRTC 1.0.22672, now i switched to last version 1.0.26885. previously i used this code to create PeerConnectionFactory And VideoSource Object and it worked fine:

PeerConnectionFactory.InitializationOptions initializationOptions =
            PeerConnectionFactory.InitializationOptions.builder(this)
                    .createInitializationOptions();
    PeerConnectionFactory.initialize(initializationOptions);

    //Create a new PeerConnectionFactory instance - using Hardware encoder and decoder.
    PeerConnectionFactory.Options options = new PeerConnectionFactory.Options();
    DefaultVideoEncoderFactory defaultVideoEncoderFactory = new DefaultVideoEncoderFactory(
            rootEglBase.getEglBaseContext(),  /* enableIntelVp8Encoder */true,  /* enableH264HighProfile */true);
    DefaultVideoDecoderFactory defaultVideoDecoderFactory = new DefaultVideoDecoderFactory(rootEglBase.getEglBaseContext());
    peerConnectionFactory = new PeerConnectionFactory(options, defaultVideoEncoderFactory, defaultVideoDecoderFactory);


    //Now create a VideoCapturer instance.
    VideoCapturer videoCapturerAndroid;
    videoCapturerAndroid = createCameraCapturer(new Camera1Enumerator(false));


    //Create MediaConstraints - Will be useful for specifying video and audio constraints.
    audioConstraints = new MediaConstraints();
    videoConstraints = new MediaConstraints();

    //Create a VideoSource instance
    if (videoCapturerAndroid != null) {
        videoSource = peerConnectionFactory.createVideoSource(videoCapturerAndroid);
    }

but in latest version i have two errors on new PeerConnectionFactory... that says:

'PeerConnectionFactory(long)' is not public in 'org.webrtc.PeerConnectionFactory'. Cannot be accessed from outside package

and on peerConnectionFactory.createVideoSource...

that syas:

createVideoSource (boolean) in PeerConnectionFactory cannot be applied to (org.webrtc.VideoCapturer)  

How can i solve these errors?

and can someone tell my WHY there is no documentation or change-log for android native WebRTC?!

Answer 1

How can i solve these errors?

There are many APIs has been deprecated or removed from WebRTC newest version. Please do the following steps to resolve those errors.

Step 1: Change your code from

peerConnectionFactory = new PeerConnectionFactory(options, defaultVideoEncoderFactory, defaultVideoDecoderFactory);

to

peerConnectionFactory = PeerConnectionFactory.builder()
        .setOptions(options)
        .setVideoEncoderFactory(defaultVideoEncoderFactory)
        .setVideoDecoderFactory(defaultVideoDecoderFactory)
        .createPeerConnectionFactory();

Step 2: Change your code from

//Create a VideoSource instance
if (videoCapturerAndroid != null) {
    videoSource = peerConnectionFactory.createVideoSource(videoCapturerAndroid);
}

to

//Create a VideoSource instance
if (videoCapturerAndroid != null) {
    SurfaceTextureHelper surfaceTextureHelper = SurfaceTextureHelper.create("CaptureThread", rootEglBase.getEglBaseContext());
    videoSource = peerConnectionFactory.createVideoSource(videoCapturerAndroid.isScreencast());
    videoCapturerAndroid.initialize(surfaceTextureHelper, getApplicationContext(), videoSource.getCapturerObserver());
}

Can someone tell my WHY there is no documentation or change-log for android native WebRTC?
